DRAW-BAR ATTACH M ENT.

SPECIFICATION forming part of Letters Patent No. 411,477, dated September 24, 1889.

Application filed June 12, 1889. Serial No. 313,976. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN TURNER, a citizen of the United States, residing at Detroit, in the county of \Vayne and State of Michigan, have invented certain new and useful Improvements in Attachments to Draw- Bars, of which the following is a specification, reference being had therein to the accompanying drawings. A

This invention relates to new and useful improvements in draw-bars; and the invention consists in the improved bearing, by means of which the draw-bar in railway-cars is supported between the draft-timbers, all as more fully hereinafter described, and shown in the accompanying drawings, in which Figure 1 is a plan view of a draw bar of the usual construction and provided with my improved bearing. Fig. 2 is a cross-section thereof on line on w in Fig. 1, and Fig. 3 is a detached perspective view of the hearing.

A are the draft-timbers of a railway-car.

I5 is a draw-bar of the ordinary construction.

0 is a bearing supporting the front end of the draw-bar, and D is the shank or reduced portion of the rear end of the draw-bar, by means of which it is supported to the draft in the following manner: E is a hollow castmetal bearing-block provided with a central horizontal tube F for the shank of the drawbar to pass through. G are vertical ribs formed in the center of the sides of the bearing-block, and II are interior partitions or webs at right angles to each other to impart the necessary strength to the bearing-block without undue weight of metal. This bearing-block is secured between the draft-bars by forming recesses in their inner sides corresponding to the size and shape of the sides of the bearing-block, as shown, and by means of transverse bolts 1, of which there are preferably four in number-two on each side of the central ribsthe bearing-block is firmly secured in position.

.T and J are the usual draft and buffer springs, which are secured upon opposite sides of this bearing, suitable washers K being used to form abutments for the springs.

It will be seen that with the bearing-block constructed and secured in this manner the shank of the draw-bar has an extended bearing in the bearing-block and cannot wear out, as with the f0llower-plates generally in use, which are apt to cut the shank and cause breakage; furthermore, the manner of securing this bearing-block imparts great strength to the draft attachment.

V hat I claim as my invention is 1. The herein-described draw-bar bearing, consisting of a rectangular casting having a central tube therein to receive the reduced end of the draw-bar, and vertical and horizontal webs formed integral with the tube and the interior of the casting, substantially as described.

2. The herein-described draw-bar bearing. consisting of a rectangular casting havingv a central tube in which the reduced end of the draw-bar bears, vertical and horizontal webs formed integral with the tube and interior of the casting, and vertical ribs in the exterior of the casting, all substantially as and for the purpose described.

3. In combination with the draw-bar timbers and draw-bar, a rectangular casting having exterior ribs fitting in the timbers, a central tube forming a bearing for the reduced end of the draw-bar, and vertical and horizontal webs formed integral with the tube and the exterior of the casting for sustaining the said tube, substantially as described.

In testimony whereof I affix my signature, in presence of two witnesses, this 3d day of June, 1889.

JOHN TURNER.
